To f/.ZZ ywhom it may concern.'

Be 1t known that I, JLIAN EARL'MONT- comuni, a citizen yof the United States, r'e

siding at Wheeling, in the county .of'Ohio -`and State of Test Virginia, have invented a new and useful. Rolling-Mill Coupllng,

p of which the following is a speciiicatiom:

' and coupling box in properposition rela- The present 4invention .appertains to rolling mill couplings, and 'aims to prpvidea novel and improved coupling device' for connecting .the `spindlewvith the roll 'of aV rolling mill, the device being'designed for; f;

at Land" 5.,' refspectively, and the coupling vbox 1 is provided with a longitudinal opentaking up the Wear, for holding the spindle tive .to one another, toprevent backlash.. when a train of rolls are coupled together and to hold the coupling box in proper en gagenient ywith the roll. linien the coupling boxes and spindles be- 1 come Worn, theyV permit the rolls to run," ,ahead and causeasildde'n'stop,just as' thepiece which is Ibeing rolled' leaves the4 r'olls,

j which, results in a backlash' due to therolls e 'advanced speed ahead of the spindle, and it is the objec'toi'. the invention to prevent the rollsirom-getting ahead of thev spindles, by

keepingthe coupling box tightagainst the y driving side of the spindle. A

The present device is adjustable and* also enables the coupling box to be slipped back on the spindle when the roll is removed 'or replaced. n 1" f lt is alsovvithin the scope of the invention to provide a device of the nature' indicated which isl coinparaifively` simple and in- 4expensive inv construction, which can be readily used in rolling mills Without entailing prohibitive trouble and expense, and Whichwill serve-its oilice 'in a thoroughly practical andefiicient manner. Yliththe foregoing and otherobjects 1n view which Will appear as the description proceeds, the invention resides in the cornbination and arrangement .ofiparts and in the details of construction herelnafter. de-

y scribedand claimed, it lbeing understood that changes 1n the precise embodiment of the invention' herein disclosed can be .made Within the scope of What 1s claimed vvlthoutil departing from the spirit of theinvention."l

The invention is illustrated in the accompanying drawings, Wherein: A Figure l. is a sideelevation of the coupling device constructed in accordancevvith the invention.. Fig. is a cross section taken on the liuc of Fig. l. Fig. 3 is a'sectional detail taken on the line of Fig. 1.4 l fraginental detail illustrating the forkr4 Y' In the drawings, there is depicted the coupling boxor member l which `is of cylindri? cal.form,.a 'nd which couples together thel adjacent ends of the spindle 2 and roll 3 of the rollingmilhsaid spindle and roll being in allnementor beingcoaxial, theneck of the roll 3 only being illustrated. The' adjacent end portions 'ofthe spindle and rollare of crucii'oriny onnon-circular cross section, as

ing @extending from end to end, and of cruciformbr non-circlilar contour to loosely.

receivethe adjacent ends of the spindle and ,I1/cousrotationptheroll being driven by the spindle. VThe spindle 2 is provided with an `oiuzstandin'g annularilangge or collar 6 between the portion l{Land-the body portion of the spindlevvhich is cylindrical. The fore-A .goingparts are common. in rolling mills,

but used by themselves, are objectionable for the 'reasonsf above indicatedV and for other familiar reasons.

i- In carrying outthe present invention, the

l,spindle end of thecouplin'g box. l is 4pro- .having an inwardly projecting/lug 11 entering tle respective end convolution of the spring to center the spring and head 10 rela tive to one another. The heads 10 have outl standing lugs or bosses l2.

Mounted for rotation upon lthe spindle end of the box 1 is a ring`13 having four ini.i'ol1,'vvhereby to connect'them for simulta- Wardly projecting cams 14 at its outer edge A overlapping ,the lspindle end ofthel box l, .and bearingy againstthey studs 12,v so that when the 'rin-g 13 is rotated in one directie openings ,8., further, thereby-compressin g the .springs 9 and increasing the tensionthereof.

The spindle endof the boxl has a pair of diametrioallyopposite outstanding lugs ics the camsltvvi-ll force the heads 10 into t e 15 through whichV adjusting screws 16 are threaded to bear against the ends of two diametrically opposite cams 141, whereby when said screws 16 are projected from the lugs 15, they will rotate the ring 13 in the direction for bringingthe springs 9 under greater tension. When the screws 16 are retracted to remove the cams 1st from the bosses 12, the ring 15 can be slipped oif of the box 1 and moved back onto the spindle.

In order to yieldably move the coupling box 1 into engagement with the end portion or Wabble 5 of the roll 3, spring means are disposed between the spindle and coupling box, and to this end a pair of diainetrically opposite lugs 7 are each provided remote from the box 1 witha pair of outstanding ears 17 and the web 18 therebetween and oi' shorter length thair'the ears 17. The end fork 19 of a bolt or rod 20 straddles the web 18 between the cars 17, to be held in place thereby, and adjusting nuts 21 are threaded upon the bolt 20. A coiled expansion spring 22 is disposed between the nuts 21 of each bolt 20 and the shoulder 26 formed by the collar (S at the respective ends of the recesses of the portion el, centering pins 24 .being threaded into the shoulder 23 for holding the adjacent ends ot the springs 22 in place. By adjusting the nuts 21, the tensions of the springs 22 can be adjusted as desired, andsaid springs in tending to expand will force the coupling box 1 away from the spindle toward the roll, thereby holding the box and roll assembled, to prevent their accidental detachment.

l/Vhen it is desired to remove or replace the roll, it is necessary to slip the box 1 back onto the spindle, and this can be readily done by disengaging` the vtoi'ks 1S) from the Webs 18, the nuts 21 being loosened if necessary. Then, when the bolts 20 and springs 22 are removed, the box 1 can lic moved freely to retracted position, whereby the roll can either be removed or applied whichever is the case.

" When the ring 13 is adjusted for cointhe springs'being readily adjusted as above j indicated.

The parts may be readily 'assembled and factured and installed.

1t is to be tinted that the springs 22 permit the spindle and roll toyield longitiidif separated, and can be inexpensively manunall or axiall f relative to one another and this is of special advantage when a series of rolls are coupled together, for should one roll breakat van angle, to force the sections thereofl apart longitudinally, the springs 22 would give and thus prevent end .thrust on other rolls.
